The specific embodiment
Below in conjunction with accompanying drawing, provide a preferred embodiment of the present invention, to describe technical scheme of the present invention in detail.
As shown in Figures 1 to 4, the on-Line Monitor Device of the UV radiation dose for ultra violet sterilizer of the present invention comprises: a lamp assembly that comprises several ultraviolet lamp tubes 1, one motor and an electric machine support 3, one connecting rod 4, wherein, lamp assembly is provided with for the fixing tube stand 2 of ultraviolet lamp tube 1, and connecting rod 4 one end are connected with the mandrel of motor, and its other end is connected with a ultraviolet probe 5 that carries out information gathering and monitoring.Every ultraviolet lamp tube 1 is covered with a quartz socket tube.Electric machine support 3 is fixed on a side of tube stand 2.Under the driving of motor, mandrel drivening rod 4 rotations by motor, by one with ultraviolet probe 5 signal being electrically connected to and power control systems, control ultraviolet is popped one's head in and 5 is carried out information gathering, the on-line monitoring of the UV radiation dose while realizing ultraviolet disinfection.Connecting rod 4 can adopt any one in a straight-bar, a curved bar and a pole, can also be a kind of multistage connecting rod certainly.When connecting rod 4 adopts multistage connecting rod, micromachine can be set between connected connecting rod and realize the connecting move control between multistage connecting rod.Wherein, the microcontroller of above-mentioned micromachine part and signal and power control system that ultraviolet is popped one's head in are partly prior art, and therefore not to repeat here.
As depicted in figs. 1 and 2, when ultraviolet lamp tube 1 is placed for horizontal, the plane of movement (or rotational plane) at connecting rod 4 places should keep and the angled α of ultraviolet lamp tube 1 place plane, such as can be that the present embodiment is 20 degree from any angle between 0 degree to 90 degree.And connecting rod 4 can be from 0 degree rotation to 180 degree in the rotational plane at its place.In testing process, by Electric Machine Control connecting rod 4, do the rotation of certain angle, keep ultraviolet to pop one's head in 5 place planes in whole motor process, keep with the plane parallel at all ultraviolet lamp tubes of lamp assembly 1 place or become certain α angle, the distance of ultraviolet probe 5 and ultraviolet lamp tube 1 place plane also from low to high, become from high to low again cyclically-varying, and then measure the UV radiation intensity at ultraviolet lamp tube 1 different distance place, so just can carry out the on-line monitoring of the UV radiation dose of ultra violet sterilizer of the present invention.
Below with shown in Fig. 1 to Fig. 4, it is example that the anglec of rotation of connecting rod 4 is respectively the situation of 30 degree and 90 while spending, and further illustrates test and the analytic process of this device:
As shown in Figure 3 and Figure 4, when the plane of movement at connecting rod 4 places and ultraviolet lamp tube 1 place plane at an angle, such as, as shown in Figure 2 20 while spending, if the angle of now connecting rod 4 rotations is respectively 30 degree and 90 degree, suppose the long L of being of bar of connecting rod 4, first calculate the vertical dimension of ultraviolet probe 5 in the plane of movement at connecting rod 4 places, again this vertical dimension is projected in the horizontal plane at ultraviolet lamp tube 1 place, by twice Hook's law computing, so obtain the distance d1=L*sin30 ° of * tan20 ° that ultraviolet probe 5 projects to the plane at the 3rd ultraviolet lamp tube place, and ultraviolet probe projects to distance d2=L*sin90 ° of * tan20 ° of the plane at the 3rd ultraviolet lamp tube place.
The unit distance of supposing contaminated water body of the real work moment is A to ultraviolet radiation actual absorption, and having the quartz socket tube of dirt is a to the actual absorption value of ultraviolet radiation, and pure water is A to the initial absorption value of ultraviolet radiation
0, the initial absorption value of clean quartz socket tube ultraviolet radiation is a
0.Therefore, constantly, there is the quartz socket tube of dirt with certain in the water quality of polluting, compares original state in real work, be under pure water and clean quartz ampoule, obtain respectively the variation delta D of the measured value of ultraviolet probe 5 rotations to the 3rd tubes and directly over the second tubes
